DTI2: Diffusion Tensor Imaging: more fractional anisotropy profiles and outcomes
Description
A diffusion tensor imaging dataset used in Swihart et al. (2012). Mean
diffusivity profiles for the corpus callosum (cca) and parallel diffusivity
for the right corticospinal tract (rcst). Accompanying the profiles are the
subject ID numbers, visit number, and Paced Auditory Serial Addition Test
(pasat) score. We thank Dr. Daniel Reich for making this dataset available.Details
If you use this data as an example in written work, please include the
following acknowledgment: ``The MRI/DTI data were collected at Johns
Hopkins University and the Kennedy-Krieger Institute"
Note: DTI2 uses mean diffusivity of the the corpus callosum rather than
fractional anisotropy (FA), and parallel diffusivity of the rcst rather
than FA. Please see the documentation for DTI for more about the DTI
dataset.References
